UPDATE 6/12/2023: the crashes have been fixed as of the 2.14 release from June 1, 2023. Thanks for your patience!
━━━━━━━━━━━━━━━━━━━
I’ve been made aware of some crashes reported by a few users. Actively looking into the issue. Apologies for the frustrations caused by it
Daylight Savings issue
Today by accident I discovered that Daylight Savings knocked out one hour from the Start/End time picker controls in Sola, with crippling effects on usability. This only happens once a year in the spring when we lose one hour to Daylight Savings. Will deploy the fix soon. In the meantime, apologies to all users who experienced the issue.
New version 2.9 of Sola released
Just released a new version of Sola featuring a more robust source of UV index forecast data provided by Weather.
How Sola can help prevent skin cancer
Sola got another review in Apps to Detect Skin Cancer Melanoma Early by App Pearl. While Sola is not designed to detect skin cancer, it will definitely help you minimize the risk of UV over-exposure, which is one of the main causes of melanoma.
Sola featured in Best Health Apps
Sola got a review by the wonderful team at Free Apps for Me, a professional app review site. You can read the article here: Best Health Apps.
Vitamin D Tracking
Added a new feature to the app that tracks vitamin D production. If you haven’t downloaded the app, give it a try – first week FREE!
Affected users who purchased version 1.25
Update 3/2/2021: this has been fixed. Users should be able to restore their purchases now.
Users who purchased version 1.25 are presented with a paywall screen and cannot restore their purchases. I have just released a fix and Apple should be approving it within the next few hours. Once the release is approved, affected users will be able to restore their previous purchase. Apologies for the inconvenience!
App Store review from Germany
Thought I’d share this review from Germany:
Couldn’t recommend the app more. You can see that someone really thought this through with superb execution. Current UV Index, pulled from the Internet, is part of the calculation. Everything else can be adjusted from skin type to base tan, to the sun protection factor of the sunscreen used, and the history of the previous exposures! There is a web page for the app on which the app is explained in detail. This is the best of all the apps I’ve seen, even if it’s only in English.
Original: Kann die App nur weiter Empfehlen. Man sieht, dass sich hier wirklich jemand Gedanken darüber gemacht hat und dieses Super umgesetzt umgesetzt hat. UV Index wird über Internet abgerufen und fließt in die Berechnung der Dauer ein, steht’s aktuell. Es lässt sich alles einstellen von Hauttyp bis Bräune übern Lichtschutzfaktor der verwendeten Sonnencreme, über Historie der genommen Sonnenzeit von den lätzen Tagen alles vorhanden! Es gibt zu der App eine Web-Seite auf der die App Ausführlich erklärt wird. Das ist das Beste was ich bisher von allen Apps die es gibt was ich gesehen habe, auch wenn nur in Englisch.
